Why Measuring the Laptop Screen Size Matters?

Knowing the exact measurement of your laptop screen is important whether you need it for purchasing any screen or laptop accessories or for building a new gadget (such as a laptop holder) for your laptop.

Most people confuse screen resolutions and screen size, which is not correct. Screen resolution measures the number of pixels that are displayed on the screen whereas screen size measures the physical dimension of the screen (usually measured in inches).

This confusion occurs because

• Two laptops can have similar screen resolutions but different screen sizes. For example, both 15.4 Inch laptops and a 14Inch laptop can have a Full HD (1920×10290 Pixels) screen.
• Two laptops with similar screen sizes can have different resolutions. This scenario is common with laptop manufacturers to cut the cost and consumer price. For example, two laptops with 14 Inch screen sizes may be available with a screen resolution of either 1600×1200 Pixels and 1920×1080 Pixels.

Here is a good comparison of screen sizes and screen resolution. That can help you to understand the difference between both and which one to use to describe it.

Screen Resolution (Pixels)	Screen Size (Inches)	Mega Pixels	Common Laptop Model
1440×900	14”	1.30	ThinkPad T400
1280×1024	14”, 15”, 15.7”	1.31
1400×1050	12.1”, 14”, 15”	1.47
1680×1050	15.4”	1.76
1600×1200	14”, 15”, 16”	1.92
1920×1080	17”, 15.4”	2.30	ThinkPad P51
